“…In recent years, poly(1,4-phenylene ether ether sulfone) (PPEES) was studied for its practical application as a separation membrane, mainly due to its high thermal resistance, film-forming capacity, good chemical stability, good solubility, and easy preparation with low-cost [ 14 , 15 ]. Our previous research revealed that PPEES could be used to prepare ultra- and nano-filtration membranes for polyphenolic compound concentration from natural extracts [ 5 , 16 ]. However, due to its hydrophobic nature, PPEES is easily fouled, resulting in a gradual decrease in permeate flux.…”

This study presents the preparation of hybrid nanofiltration membranes based on poly(1,4-phenylene ether ether sulfone), polyacrylonitrile, poly(vinyl pyrrolidone), and SBA-15 mesoporous silica. Laser treatment of polymeric solutions to enhance the hydrophilicity and performance of membranes was investigated. The membranes’ structure was characterized using scanning electron (SEM) and atomic force (AFM) microscopy and contact angle measurements. The addition of PAN in the casting solution produced significant changes in the membrane structure, from finger-like porous structures to sponge-like porous structures. Increased PAN concentration in the membrane composition enhanced the hydrophilicity of the membrane surface, which also accounted for the improvement in the antifouling capabilities. The permeation of apple pomace extract and the content of polyphenols and flavonoids were used to evaluate the efficacy of the hybrid membranes created. The results showed that the hybrid nanofiltration membranes based on PPEES/PAN/PVP/SBA-15: 15/5/1/1 and 17/3/1/1 exposed to laser for 5 min present a higher rejection coefficient to total polyphenols (78.6 ± 0.7% and 97.8 ± 0.9%, respectively) and flavonoids (28.7 ± 0.2% and 50.3 ± 0.4%, respectively) and are substantially better than a commercial membrane with MWCO 1000 Da or PPEES-PVP-based membrane.

Aims: Panitumumab (anti-Erb)-conjugated polycaprolactone (PCL) nanoparticles loaded with bosutinib (BTNB) were used to develop a targeted drug-delivery system for colon cancer cells. Materials & methods: Using carbodiimide coupling, anti-Erb was conjugated to BTNB-loaded PCL nanoparticles. Dynamic light scattering, scanning electron microscopy, transmission electron microscopy, Fourier-transform infrared spectroscopy, differential scanning calorimetry, x-ray diffraction and thermogravimetric analysis were used to analyze nanoparticles. Results: According to in vitro studies, anti-Erb-BTNB-PCL nanoparticles inhibited HCT116 cells more than BTNB alone. Cell arrest at different phases was examined for apoptotic potential. An in vivo efficacy study showed that anti-Erb-BTNB-PCL nanoparticles could target tumors selectively. Conclusion: Anti-Erb-conjugated BTNB nanoparticles could specifically target colon cancer.
